I've deployed a war file into Tomcat 8 and am attempting to hook up authentication with Shibboleth. When I go to my login page, my Shib IdP accepts my credentials with apparent success, but then I get redirected infinitely between Shibboleth IdP and my Tomcat application.

The only error I have come across so far is the below in the Tomcat logs. Bumping the logging level all the way up doesn't generate any further detail. Would appreciate any thoughts/advice.

Every time I've set up Shibboleth eventually ending with Tomcat, I've had to use Apache reverse-proxy since there wasn't (isn't?) an SP written to interface directly with Tomcat. The Apache setup is pretty straightforward, have you tried that?
